[UpdateTestChecks] Fix PowerPC RE to support AIX assembly

Current cannot generate checks for AIX
(powerpc64-ibm-aix-xcoff) properly. Assembly generated is little bit
different from Linux. So I use begin function comment here to capture
function name.

[RISCV] Rename RVV intrinsics class (NFC)

Rename the class `RISCVUnaryAAMask` to `RISCVBinaryAAAMask`, since it has two input arguments.
